Abstract:

Based on the multicenter network urban theory and cluster network structure competition theory,depended on the building of urban spatial network structure performance analysis framework and evaluation index,we used DEABCC model and DEAMalmquist index model to analyze the space network contact efficiency of 42 cities around the Poyang Lake during the year 2008 to the year 2010.The following conclusions are put forward in this paper.(1)Most cities around the Poyang Lake were in the spatial network contact of production frontier surface,and cities which were not in production frontier area are gradually moving to the production frontier surface by the comparison of efficiency.(2)From the efficiency decomposition,the change of the space network structure performance of cities around the Poyang Lake was affected by the technical efficiency and technical level transformation, and technical level had a visible effect on it.(3)On the distribution of efficiency of spatial difference,the spatial network structure performance of cities around the Poyang Lake presented the regular that performance of center zone is higher than that of the marginal zone,and performance of the marginal zone is better than that of the peripheral zone.However,the speed of urban space network development showed a regular that marginal zone has the fastest speed,followed by the center,and the peripheral zone has the slowest speed
